In 1996 DDRH was the first (and it still is today) electric-hybrid rotocraft single-seat project. It flies thanks to a combination of four flattened electric-three-phase motors (two on each side) digitally controlled by a special computer and a turbine-power-generator.

In this project I inserted for the first time a single tactile screen as the main instrument-control panel, even though it was at the time quite primitive compared to contemporary technologies available. More on my site.
